Not only did the Colts not attend his pro day, the Colts were I think the only top 10 team in the draft that did not interview him at the combine. Robert Griffin III made sure to tell the media that in his on-the-field interview with the media after the combine.

if thats the case and irsay invited me to attend a private work out (for nothing more than a dog and pony show to gain leverage with luck's agent) i'd tell them to shove the extra million and #1 draft pick up their ass.
